Abstract

The complex compound tetrakis(N,N’-diethylthiourea)bis(isothiocyanato)nickel or [Ni(detu)4(NCS)2] (denoted as UMCC-1) has been synthesized by reflux method in two different solvents namely acetone and methanol. This study aims to synthesize, characterize, and analyze the Hirshfeld Surface complex UMCC-1, which was obtained using the reflux method with the mole ratio of NiCl2: detu: KSCN is 1:2:4. Single crystals UMCC-1 in acetone and methanol are dark green in color with melting points of 135-137°C and conductivity of 66.4-84.4 µS. The FTIR absorption band analysis of the two crystals is very similar, ν(C S) detu 590 cm−1 and ν(C≡N) isothiocyanate 2119 cm−1. The refinement of the crystal structure from the single crystal XRD data shows that the two dark green crystals are a molecular type that has a distorted octahedral geometry with the same crystal lattice, monoclinic crystal lattice, P21/c1 space group (no.14), crystal lattice parameter a= 11.112(3) Å, b= 17.249(5) Å, c= 9.647(3) Å, and β= 100.785(10). However, the complex produced in acetone solvent has better refinement quality than methanol concerning %R= 3.27 and %R = 4.55, respectively. The UMCC-1 crystal shows intermolecular hydrogen bonds N-H---S(isothiocyanato) and intramolecular hydrogen bonds N-H---S(detu) with Hirshfeld Surface analysis showing a significant contribution of H---H (69.5%) on crystal packing.

Abstract

The Majapahit plant is commonly found in Indonesia but is rarely used due to a lack of information about its potential. One of the secondary metabolites commonly found in this plant are flavonoids. Therefore, this study aims to determine the distribution of flavonoid compounds in the Majapahit plant, particularly their potential as anticancer activty. Leaf material from Majapahit plants was extracted using the maceration technique, while the flavonoid compounds in the extract were identified using LCMS (Shimadzu LCMS-8040 LC/MS). The identification results showed that about 97 compounds were detected, including 14 flavonoids. The flavonoid compounds found include Quercetin, Chlorogenic acid, Kaempferol 3-O rhamnoside, Acacetin 7-rutinoside, Fortunellin, Kaempferol 3-[6"-(3-hydroxy-3-methyl glutarl) glucoside], Didymin, Diosmin, Hesperidin, Rutin, Citrusoside C, Citrusoside D, Narirutin 4'-glucoside, and Kaempferol 3-[6"-(3-hydroxy-3-methylglutaryl)glucoside] -7-glucoside. The highest composition of the identified flavonoid compounds was found in Kaempferol 3-O rhamnoside, with a 3.90%

Abstract

The Indian Borage plant (Plectranthus amboinicus) is a traditional medicinal ingredient in Indonesia, containing flavonoids, alkaloids, polyphenols, saponins, and essential oils. Therefore, this study aimed to determine the antibacterial activity of P. amboinicus leaves ethyl acetate fraction using the disc diffusion method and identify the composition with LC-MS. The antibacterial activity test was conducted with concentration variations of 15%, 20%, and 25% with Chloramphenicol 500 mg and 5% DMSO as a positive and negative control, respectively. The results showed that the ethyl acetate fraction at a concentration of 20% had the largest inhibition zone diameter, with an average of 30 mm. The LC-MS results identified 115 compounds, and the highest concentration values were found in kaempferol 3-(6”-caffeoylglucoside) and kaempferol 3-glucosyl-(1→2) galactosyl-(1→2)-glucoside, with a composition of 3.26109% and 3.26141%, respectively.

Abstract

Zinco-phosphate having CZP structure (CoZnPO-HEX) has a potential as a catalyst in Knoevenagel condensation of benzaldehyde with activated methylenic compounds or the Michael addition of nitroethane to olefin. The potency is led by the physicochemical properties of the material, which depend on its crystal habits. Understanding the crystal growth of materials is important to be able to design and control their crystal habits.  Therefore, the crystal growth study of CoZnPO-HEX is crucial for its crystal habit modification as well as for optimization and expansion of the material’s functions. Several parameters of crystal growth, such as nucleation time, gel supersaturation, and crystal size changes during the synthesis process can be analysed by observing the material’s crystallisation profile. In this study, crystallisation analysis was performed on CoZnPO-HEX, synthesised using solvent-free method, from its crystallinity curve based on Powder-XRD data supported by SEM data. As a comparison, crystal growth simulation was performed using CrystalGrower program to determine the morphology, surface topography, and theoretical crystal growth mechanisms. From this study, we found that the nucleation time of the CoZnPO-HEX crystals prepared using a solvent-free method took place during the precursor grinding process at room temperature. The crystal morphology of the as-prepared materials agrees well with the simulation’s one. Moreover, the CrystalGrower simulation proved that the smallest t-czp-1 tile started the nucleation on the crystal surface because of its low free energy.

Abstract

Penelitian ini mengungkapkan potensi senyawa flavonoid dalam daun jinten (Plectranthus amboinicus) sebagai agen antikanker. Melalui identifikasi menggunakan Liquid Chromatography-Mass Spectrometry (LC-MS), ditemukan delapan senyawa flavonoid, termasuk Kaempferol 3-(5''-feruloylapioside), Kaempferol 3-(6''-caffeoylglucoside), dan Kaempferol 3-glucosyl-(1 2)-galactosyl-(1 2)-glucoside. Senyawa-senyawa ini telah terbukti memiliki potensi antikanker melalui penelitian sebelumnya. Metode LC-MS dipilih untuk identifikasi senyawa karena memberikan data yang informatif, termasuk informasi tentang massa molekul senyawa yang teridentifikasi. Proses penelitian melibatkan beberapa langkah, mulai dari pembuatan simplisia daun jinten, pembuatan ekstrak melalui maserasi, fraksinasi, hingga identifikasi senyawa menggunakan LC-MS. Temuan ini mengindikasikan bahwa daun jinten memiliki potensi sebagai sumber senyawa antikanker yang bernilai, yang dapat menjadi dasar untuk penelitian lebih lanjut dalam memanfaatkannya dalam terapi kanker.

Abstract

COVID-19 not only brings problems to physical health but also mental health, such as anxiety. Excessive anxiety is very dangerous because it can reduce the number of white blood cells in the bloodstream. Excessive anxiety also triggers the production of excess cortisol which interferes with the immune system. This could be overcome by the combination of tea which has a relaxing effect with several immunomodulatory herbs. Green tea (Camellia sinensis) has been shown to have the effect of reducing one's anxiety and improving one's psychological health. The tea is combined with other spices, namely (Zingiber officinale), turmeric (Curcuma domestica Val), and cinnamon (Cinnamomum burmannii). This study was conducted to find out that the combination formed has met safety standards, so it can be used as an immunity-boosting drink during a pandemic. Standardization includes testing for moisture content, ash content, and organoleptic tests. The results obtained were the water content of herbal tea was as much as 6.26%, while the ash content of the tea was 5.74%. The water content and ash content had met the standards of the Ministry of Health regarding the preparation of herbal medicines. The organoleptic test performed showed that the formulation obtained was dominated by the taste of ginger, the color of turmeric, and the smell of cinnamon.
